Honestly If anyone just come into crypto space through a link or online ads it's easier to get lost and fall victim to scams, i never get hacked for once or lost money to scam projects simply because I favoured learning things I don't know anything about, why can't people be like this either? This will easily safe you from money doubling schemes and Ponzi schemes, please newcomers and members, be more willing to learn.
I agree, but you can't really blame people for being gullible enough to invest on crypto and lost money, specially if you're a beginner. I personally lost some, not in ICO, but on a bitcoin double years ago. I was just a newbie then, and I thought why not? so I invest and it's good because I was able to get a pay. But then I re-invested it again. And sadly, the scammers pull an exit scam.
It was really an eye opener for me and I have learn my lessons very expensive one. Anyways, I move forward never trust anyone with my precious cryptos.
